id: CVE-2021-33221

info:
  name: CommScope Ruckus IoT Controller - Information Disclosure
  author: geeknik
  severity: critical
  description: CommScope Ruckus IoT Controller is susceptible to information disclosure vulnerabilities because a 'service details' API endpoint discloses system and configuration information to an attacker without requiring authentication. This information includes DNS and NTP servers that the devices use for time and host resolution. It also includes the internal hostname and IoT Controller version. A fully configured device in production may leak other, more sensitive information (API keys and tokens).
  remediation: |
    Apply the latest security patches or updates provided by CommScope to mitigate the information disclosure vulnerability (CVE-2021-33221).
